A new storage engine, MyRocks, that gives you high compression of your data without sacrificing speed. It has been developed in cooperation with Facebook and MariaDB to allow you to handle more data with less resources.

flashback, a feature that can rollback instances/databases/tables to an old snapshot. The version in MariaDB 10.2 is DML only. In MariaDB 10.3 we will also allow rollback over DML (like DROP TABLE).

InnoDB is now the default storage engine. Until MariaDB 10.1, MariaDB used the XtraDB storage engine as default. XtraDB in 10.2 is not up to date with the latest features of InnoDB and cannot be used. The main reason for this change is that most of the important features of XtraDB are nowadays implemented in InnoDB . As the MariaDB team is doing a lot more InnoDB development than ever before, we can't anymore manage updating two almost identical engines. The InnoDB version in MariaDB contains the best features of MySQL InnoDB and XtraDB and a lot more. As the InnoDB on disk format is identical to XtraDB's this will not cause any problems when upgrading to MariaDB 10.2
